Report generation not working

[MichaelAntonFischer]

Describe the problem/bug
Sometimes the report generation doesn't work, the loading symbol just stays on. Also, if you generate report for one month and then click on the next month, a report will be downloaded that has the data from the previously selected month, but is labeled like the newly selected month.

Your environment

• Version of ThunderHub: 0.13.29
• Deployment method: Docker

To Reproduce
Steps to reproduce the behavior:

1. Go to report
2. Click on 'generate'
3. Click on next month

We found out that this issue is caused by large lightning nodes, if one waits long enough and the browser session is stable, then the report eventually downloads.

We noticed another issue however:
If you just created a report and then click on a different month, the report will immediately download, but it will really be the report from the previous month, just labeled differently.

P.S. It would also be appreciated if the selected year would automatically be the current year, when entering the reports page.
